According to a source close to the situation, Rooks will decide for the University of Memphis and become the eighth commitment of the Tigers' 2012 class.
Rooks' commitment also means that, of the eight commitments U of M coach Larry Porter has received, six are from the Memphis metro area.
"I like the environment and all (at Memphis), mostly because it's my home and they welcomed me," Rooks said.
The 6-foot-5 Rooks said he weighed 327 pounds before losing weight last year. He's now at 289 pounds.
Rooks said he's watched closely as other Memphis talent has recently committed to stay home and play for the hometown Tigers.
"I want to be a part of it," Rooks said. "It's something big that Memphis is doing, keeping all the home talent and I'm with it. That's why I wanted to commit to Memphis, to stay home and keep the talent here so we can progress and win.
"I commend those guys for committing and keeping the talent here."
Rooks said a close relationship with U of M coach Larry Porter played a large role in his decision tonight.
"He's a stand-up guy," Rooks said. "He told me no lies. I trust him. I like him."
